Answer:
(-2,-36)
Step-by-step explanation:

<u>1) Find the zeros of the parabola</u>
The zero-product property states that any value, when multiplied by 0 will equal 0. Therefore, to make y=0, either (x-4)=0 OR (x+8)=0.
Therefore, x=4 and x=-8.
<u>2) Find the x-coordinate of the vertex</u>
To do this, we take the average of our zeros.

Therefore, the x-coordinate of the vertex is -2.
<u>3) Find the y-coordinate of the vertex</u>
Plug the x-coordinate back into the original equation

Therefore, the y-coordinate of the vertex is -36.
Therefore, the vertex of the parabola is (-2,-36).
I hope this helps!

Answer:
28
Step-by-step explanation:
The 5 part of the ratio represents 35 girls , then
35 ÷ 5 = 7 ← value of 1 part of the ratio, then
4 parts = 4 × 7 = 28 ← number of boys
We know that Simone is going to snowboard tomorrow if the temperature is equal to or colder than 5 degrees Celsius. Equal to or colder basically means less than or equal to. The sign for that is ≤. Since we know that t is less than or equal to 5 degrees Celsius, we can substitute the ≤ sign for less than or equal to, giving us our inequality of t ≤ 5.
Answer:
N = 82
Step-by-step explanation:
(N - 49)/11 = 3
N - 49 = 33
N = 82
